  • Javascript: Retrieve Object Property Names

    - by Jason
    I'm trying to write a function that needs to know the property names of an object being passed in, like so: var data = { "key1":"value1", "key2":"value2", etc} ^ i want the string value "key1" How do I retrieve the string "key1" from data? I know I can set a property dynamically like data[prop]=value but i want to know what prop is from an object passed in. If that doesn't make sense I suppose I could try to explain more. Thanks! I eventually want to do something like: for (var i = 0; i<data.length; i++) { var name = data[i].getPropertyName() <--- not a real function // do stuff }

  • speeding up parsing of files

    - by user248237
    the following function parses a CSV file into a list of dictionaries, where each element in the list is a dictionary where the values are indexed by the header of the file (assumed to be the first line.) this function is very very slow, taking ~6 seconds for a file that's relatively small (less than 30,000 lines.) how can I speed it up? def csv2dictlist_raw(filename, delimiter='\t'): f = open(filename) header_line = f.readline().strip() header_fields = header_line.split(delimiter) dictlist = [] # convert data to list of dictionaries for line in f: values = map(tryEval, line.strip().split(delimiter)) dictline = dict(zip(header_fields, values)) dictlist.append(dictline) return (dictlist, header_fields) thanks.

  • [jQuery] Get width of element after resizing it

    - by infinito
    Hello, Is it possible to get the size of an element after resizing it using $(el).css()? My code is: function resize() { $(".combobox").css('width', '100%'); var width = $(".combobox").width(); } I've get the real value of the combobox only after calling the function a second time. The first time is gets the width before executing $(".combobox").css('width', '100%'); I suppose this is fault of the DOM not being recreated after the .css(). Is there any way to force DOM reloading? Thanks in advance!

  • Using a string as an object reference

    - by user317362
    I currently have a Javascript function that uses a string to reference an object name and acces its properties. I'm currently using eval() to get the the desired effect which I know is very, very wrong. Here is an example of how I'm currently achieving what I want: var stringToObjectRef = function() { var myTestVar = "myTestObject"; var myTestObject = { 'item1' : 100, 'item2' : 12, 'item4' : 18 }; var myValue = eval(myTestVar + '.item1'); alert(myValue); }(); I've tried using something like [myTestVar].item1, but this returns undefined. What is the correct syntax to achieve this? Thanks in advance.

  • C++ OOP: Which functions to put into the class?

    - by oh boy
    Assume I have a class a: class a { public: void load_data( ); private: void check_data( ); void work_data( ); void analyze_data( ); } Those functions all do something with the class or one of its members. However this function: bool validate_something( myType myData ) { if ( myData.blah > 0 && myData.blah < 100 ) { return true; } return false; } Is related to the class and will only be called by it, so it won't be needed anywhere else Doesn't do anything with the class or its members - just a small "utility" function Where to put validate_something? Inside or outside the class?

  • Does '[ab]+' equal '(a|b)+' in python re module?

  • Why does this PHP program not work?

    - by oncode
    I'm new to PHP and was learning about PHP functions from w3schools. It said PHP allows a function call to be made when the function name is in a variable: This program worked <?php $v = "var_dump"; $v('foo'); ?> But this program did not work: <?php $v = "echo"; $v('foo'); ?> But if I do echo('foo'); it works. What am I doing wrong?

  • AJAX Closures and targeting 'this'

    - by Nick Lowman
    In the code example below the success callback function logs 'input#04.update' four times rather than each individual input, which makes sense seeing how closures work but how would I go about targeting each individual input using this. <input type="text" name="" id="01" class="update"> <input type="text" name="" id="02" class="update"> <input type="text" name="" id="03" class="update"> <input type="text" name="" id="04" class="update"> function updateFields(){ $('input.update').each(function(){ $this = $(this); $.ajax({ data: 'id=' + this.id, success: function(resp){ console.log($this); $this.val(resp) } }); }); }

  • PHP Case Insensitive Word Replacement

    - by zuk1
    Ok I'm trying to make search terms bold in this search script I'm making, except I can't get it to work case insensitive. function highlight($term,$target){ $terms = explode(" ", $term); foreach($terms as $term){ $result = (eregi_replace($term, "<strong>$term</strong>", $target)); } return $result; } That is the function I have so far.. It says on PHP.net that eregi_replace is case insensitive matching but it's obviously not working for some reason. (I'm a noob). Any ideas? :D

  • read after lseek always return 0

    - by Wins
    I'm having an issue reading byte in file after performing lseek long cur_position = lseek(fd, length * -1, SEEK_CUR ); // Rewind file reading by length bytes. printf("cur_position: %i\n", cur_position); int num_byte = read(fd, &byte, 1); printf("num_byte = %i\n", num_byte); With the initial variable length set to 34, the above code would produce cur_position 5 (so there are definitely at least 34 bytes after the lseek function returns), but the variable num_byte returned from function read always returns 0 even though there are still more bytes to read. Does anyone know the reason num_byte always return 0 or do I make mistake in the above code? Just for information, the above code was run on the following machine $ uname -srvpio Linux 3.2.0-24-generic #39-Ubuntu SMP Mon May 21 16:52:17 UTC 2012 x86_64 x86_64 GNU/Linux

  • how to do collision detection for hollow(?) movieclips in flash AS3?

    - by Pieter888
    Hey everyone, I'm making small interactive games in flash to learn AS3, now I ran into a problem that I need some help with. I need to check the collision between the player and the wall which is normally simple using the hitTestObject function. But now I made a wall object totally surrounding the player with corridors and turn, a collision playground so to speak. Now when I use the hitTestObject function to check whether the player is in collision with the wall it tells me it always collides supposedly because the player object is within the bounds of the wall object. So assuming that I'm correct about the error: How can I prevent getting a collision when I'm inside the bounds of the wall object but not touching the actual walls in that object?

  • Datepicker (1.8rc3) not transferring date in IE6

    - by brianjcohen
    Using jquery-1.4.2 and jquery-UI 1.8rc3, I instantiated a datepicker on a text input with showOn: 'focus'. The datepicker appears correctly. However when I click on a date, the datepicker doesn't disappear and the dateStr doesn't get transferred to the text input. I tried adding an onClose: handler that calls alert(dateStr). The event fires but no dateStr has been set. Everything works fine in Firefox. I have Microsoft Script Debugger installed but no script errors were detected. I did report this as a potential problem at the jQuery UI forums but my message has been sitting there awaiting moderation for hours and I figured someone here might have a suggestion. $().ready(function() { $(".date").datepicker({ showOn: 'focus', onClose: function(dateText) { alert(dateText); } }); });

  • this pointer to base class constructor?

    - by Rolle
    I want to implement a derived class that should also implement an interface, that have a function that the base class can call. The following gives a warning as it is not safe to pass a this pointer to the base class constructor: struct IInterface { void FuncToCall() = 0; }; struct Base { Base(IInterface* inter) { m_inter = inter; } void SomeFunc() { inter->FuncToCall(); } IInterface* m_inter; }; struct Derived : Base, IInterface { Derived() : Base(this) {} FuncToCall() {} }; What is the best way around this? I need to supply the interface as an argument to the base constructor, as it is not always the dervied class that is the interface; sometimes it may be a totally different class. I could add a function to the base class, SetInterface(IInterface* inter), but I would like to avoid that.

  • using jquery $.post() for returning multiple values

    - by Aninemity
    Hi all I am trying to use a $.post() in the following way: $.post("file.php", { file_id: $(this).val()}, function(data){...} The file.php then does a database query and returns an array with a title, description and image reference. What I want to do then is be able to update the .val() for form fields for each. I understand how to do this on a single variable, it would just be the following: $.post("file.php", { file_id: $(this).val()}, function(data){ $('#title').val(data); } But, how do I get the data returned to be recognizable in jquery as either separate variables or as an array? Thanks in advance

  • beforeSave() returned some error

    - by kwokwai
    Hi all, I got a simple input text field in a HTML form: <input type="text" name="data[User][pswd]" id="data[User][pswd]"> The scripts for the Controller's action that captured the data is as follows: function register(){ $temp = $this->data; if(strlen($temp['User']['pswd'])>6) { if ($this->User->save($this->data)) { $this->Session->setFlash('Data was Saved'); } } } // this script works And in the Model controller, I got these lines of codes: function beforeSave() { $raw = $this->data; if(strlen($raw['User']['pswd'])>6){ md5($raw['User']['pswd']); } return true; } // this script failed to work The data was stored into the Database successfully but it was not undergone any MD5 encryption. I think that there must be some errors in the Model's script because I saw some errors flashed after the data was saved, but the screen that showed the errors immediately refreshed in a second after the data was saved successfully and I couldn't see the detail of the errors that caused the problem. Could you help me out please?

  • What's the outcome if I use free with new or delete with malloc?

    - by skydoor
    It is a compiler error or runtime error? The code below can be compiled! class Base{ void g(); void h(); }; int main() { Base* p = new Base(); free(p); return 0; } However it can't be compiled with a virtual function if I declare the class Base like this class Base{ virtual void g(); void h(); }; The code below can be compiled all the time, no matter the function is virtual or not. class Base{ void g(); void h(); }; int main() { Base* p = (Base*)malloc(sizeof(Base)); delete p; return 0; }
